POLE-SUPPORT.

Specification of Letters Patent.

Patented Apr. 9, 1918.

Application led February 21, 1917. SeriaI No. 150,239.

To all whom t may concern:

Be it known that I, I-IAzEL BURTON BUSH,

a citizen of the United States, residing at Redlands, in the county ofSanBernardino, State of California, have invented a new and usefulPole-Support; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the artY to which it appertains to make and use the same.

This invention relates to a new and useful support for various kinds ofpoles, such as telegraph andtelephone poles, and the like.

One of the objects of the invention is to provide an improved support orprop to support the pole at different times, alternating with the poleerecters attaining new holds on the pole, in order to gradually standthe pole onits end and in its foundation.

A further object of the invention is to provide a support which issimple, efficient and practical in construction, and which may bemanufactured very cheaply, and will serve advantageously to obtain thedesired result, without collapsing under the weight of the pole.

A further object is to provide a support of this kind comprising twocrossing members or legs, so pivoted together at their point ofintersection as to permit the legs to be collapsed together when thesupport is not in use.

A further object of the invention is to provide a pole supporting meansor brace detachably connecting the upper ends of thetwo members or legs,and a brace pivotally carried by one leg and designed to detachablyengage means on the other leg, to prevent collapsing of the legs.

A further object of the invention is to provide feet for the legs ormembers.

In practical fields, the details of construction may necessitatealterations falling within the scope of what is claimed.

The invention comprisesfurther features and combination of parts,asfhereinafter set forth, shown in the drawings and claimed.

In the drawings Figure 1 is a View in perspective of the improvedsupport, showing the same in use.

Fig. 2 is a view in elevation of the support.

Fig. 3 is a view of the upper end portions of the intersecting orcrossing members, showing parts in section, and illustrating the poleengaging member partly in elevation and partly in section.

Fig. 4, is a.l sectional view on line L -4 of Fig. 3.

Fig. 5 is a detail view of the detachable connection ofthe lower brace.

Referring more especially to the drawings, 1 and 2 designate twointersecting members, which, at their point of intersection areconnected by the pivot ,pin 3. These members consist of angle bars, Vandwhich are reversely disposed. The upper ends'of said members or bars areprovided with bifurcations 4, which are formed inthe lateral flanges.Extending laterally from the upper ends of the bars, adjoining saidbifurcations are headed pins 5. `When the bars or Vinembers are erect,as shown in Fig. 1, a curved bar 6 is utilized. Each end of this bar 6has an L-shaped slot 7 The slots of both ends of the bar 6 are designedto engage the pins 5, thereby bracing the upper ends of the members orbars 1 and 2. A pole engaging plate 8 is provided. This plate 8 isU-shaped in cross section, in order to arch the bar 6, there beingsuitable insulation 9 in the U- part of the plate 8, thereby insulatingthe plate 8 from the bar 6. This plate 8 in elevation is curved tosubstantially conform to the cross sectional contour of the pole to beerected, and is riveted, as shown at 10, to the bar 6. The upper curvededge of the plate 8 is provided with sharp points 11 and 12, to piercethe pole, thereby preventing slipping of the support yas well asthepole. The rivets 10, where they pass through the bar 6 and theopposite walls of the U-portion of the plate 8, are also insulated, asshown at 13. By virtue of the insulation, current is prevented frombeing transmitted to the members or bars 2 and 3, should the pole bedamp, and have live wires connected thereto, and should the pole beconstructed of metal.

Connected to the member or bar 2 by means of a pivot pin 14, is a brace15. This brace, at its other end, has a notch 16 in its upper edgeportion to engage the headed pin 172L of the member 1, there being aleaf spring 17 secured at 18 to the bar or member 1, whereby the upperend edge of said leaf spring will engage the brace 15 and hold its notchin engagement with the headed pin, thereby bracing the lower portions ofthe members or bars 1 and 2. The lower portions of the bars 1 and 2constitute legs, and

secured to the lower ends of the bars or members 1 and 2 are feet 19.Each foot consists of Va wood insert block 20 secured to one oi theflanges of each leg by means of the screws 2] and 22, and also securedabout the lower ends of the foot or wood blocks by means of the screw 22is a metal wear strap or plate 23. One end of this strap engages4between the block and one flange oi? the bar or member. A suitableleather strap 211 is riveted at 25 to the bar o-r member 2 and has abuckle 26 whereby the two members or bars 1 and 2 may be clampedtogether, when` what Copies of this patent may be obtained forfurcations, a curved bar engaging said bifurcations and having L-sh'apedslots at its ends detachably' engaging said headed pins, a

pole engaging plate curved concentric with the bar and being U-shaped incross section and straddling said bar, insulating means between the barand the walls of the U- shaped portion of said pole engaging plate,means passing through the-U-shaped portion and the bar to hold the platethereto, said pole engaging plate hfwing an upstanding part to engagethe pole, and means tobrace said members at a point below theirintersection. o

In testimony whereof I have signed my name to this specification inthepresence ot two subscribing Witnesses.
